' To all whom it may concern:

Be it known that I, FREDERICK R. KEITH,

a citizen of the United States, residing at Randolph, county of Norfolk, State of Massachusetts', have inventedan Improvement in Insoles, of which the following description, in connection with the accompanying drawing, is-a specification, like characters on the drawing representing like parts.

This invention relates to insoles such as are used in the manufacture of welt boots and shoes, and the object of the invention is 'to provide a'novel insole which can be inexpensively manufactured but which has 15 all the essential characteristics necessar to an insole.

-My improved insole comprises a body element which is made thinner at its edges thereby to provide a shoulder which extends 29 parallel to but is situated at'a slight distance back from the edge, and a, rib-forming element which is positioned'by said shoulder and is secured tothe thinner edge portion of the body element. v

In order to give an understanding of my invention I haveillustrated in the drawings some selected embodiments thereof which will now be described, afterwhich the novel features will be pointed out in the appended claims.

, Figu'relis a plan view of an insole. embodying my invention; Fig. 2 is an enlarged section injperspective on the line 22, .Fig.

, 1.; Fig. '3 is a similar view-showing a differ ent embodiment of the invention; Fig. 4' is a similar view showing a'still difierentembodiment of the, invention; 5 is a view of-the' rib-bearing strip. before-the rib "is formed thereb'y. I

1 designates the bodyelement of the insole .which may be made of any suitable material.

having sufficient strength for the. "purpose. LA comparatively-cheap material, such "as Y leather board, can be successfully used; This body element ,1 is reduced in thiclmessfat its edge 2 and is formed with a shoulder 3- which extends parallel to the edge; ,A rib- I forming elementis secured to the thin edgeportion 2 of the body element and is -p0si- 'tioned by the shoulder? This rib-forming element may be madein various ways w1th-' out departing fromthe invention.-

"In Figs. 1' and 2 I have shown it he formed from a strip 4 of leather or other suitable material, such as shown'i-n-Fig. 5

' Said strip being of a width equal to thdinseam-receiving rib 19.

width of the thin edge portion 2; This strip 'is channeled at its opposite sides, as shown at 6 and 7 in Fig. 5, and the portions 8 and 9 are turned up to produce the rib that re- 'ment 4, but I will preferably use a material which is sufficiently tough and strong so that the rib which is formed by the upturned lips 8 and '9 will be strong enough to hold the inseam stitches during the manufacture of the shoe.- With an insole made in this way the body-portion 1 may be made from comparatively inexpensive material.

In Fig. 3 I have illustrated a different embodiment of the invention wherein the rib-' formingelement 40 is channeled from the outer..edge only and the rib is formed by turning up a single lip 80. In this embodiment of .the invention the face of the insole s covered by a layer 14 of canvas or other fabric which overlies the upturned lip 80 and with the latter forms the complete inseam-receiving rib 15. In this embodiment, the-strength of the fabric l haugments the strength of the single lip 80 and thus a sufficiently strong inseam-receiving rib may be produced.- p

' Fig. 4. a stilldifi'erent embodiment of the invention is. shown wherein the ribforming. element is formed by a strip'16'of fabric which is folded longitudinally and issewed to the thin edge portion 2 of the *body element 1 vby stitches 18, said folded Patented J an. 2, 1917.;

fabric being ,sewed closely adjacent the shoulder 3 and the latter serving as a guiding-or positioning means for the mem ber 16. In this embodiment of the inven-.

tion too-I have shown the insole as covered with a layer 14 of canvas or other fabric which overliesthe rib-forming strip- 16. and with the latter forms the complete In' all of the embodiments of the invention the. rib-forming element .is sewed to [the thin, edge portion2 of the body element In the embodiment shown'in Fig. 2 the channel 7 is so formed that the portion 13 of the strip 4 has a thickness equal tois thinner than the portion 13. In sewing,

the welt and upper to the insole the curved needle which is usually used in sewing ma chines for this purpose enters the rib at' the base thereof from the inner side. By having the insole thinner on the outer side of the rib, the needle will emerge from the rib on the outer side thereof above the top of the insole. This same feature is also present in the embodiment shown in Figs. 3 and 4:, for-in each of these constructions the completed insole is thinner outside of the inseam-receiving rib than it is on the inside thereof.

It will be observed that in all of the illustrated embodiments of my invention the outwardly-facing shoulder 3 is situated entirely between the top and bottom faces of the body member and that no part of the body member is employed in making the inseam-receiving rib, all of said rib being formed by material which is separate from.

but secured to the body member.

'An insole embodyingamyinvention can -be manufactured Very cheaply because relatively-cheap material can be used ,for the body element 1.

In the embodiment shown in Figs. 2 and 3 I will prefera ly makethe rib-bearing element of leather, but the invention is not confined to the use of leather for this purpose.

I claim:

1.. An insole comprising a body element having an outwardly-facing rib-positioning shoulder formed on an integral part thereof adjacent its edge, the portion of said body element between the shoulder and the edge being thinner than the rest thereof and said shoulder having a depth equal to the difference in thickness between the main thinner than the rest thereof, and a ribforming element secured to said thinner edge portion of the body element and positioned by the shoulder thereof, said ribforming element being channeled longitudinally from the outer edge and the chairneled portion being turned up to form an inseam-receivlng rib.

In testimony whereof,I have signed my name to this specification.

FREDERICK It. KEITH.
